Nico,
That is correct. Due to the design of the mplot3d module, many functions
that are expected to work for 2D plots do not work for 3D plots. I have
been working on bringing mplot3d to feature-pariety with the rest of mpl.
The upcoming release should address many of these issues. However, the
set_aspect issue is a harder nut to crack correctly.
If you need a work-around, I have a git branch where I introduce the
matlab-esque pbaspect where one can specify the ratios of the x, y, and z
axes relative to each other. Note that right now, at least one has to be
1. It does introduce some other bugs, though, which is why it won't be in
the next release.
https://github.com/WeatherGod/matplotlib/tree/mplot3d%2Fpbaspect
Keep an eye on that branch for future updates, though.
I hope this helps,
Ben Root

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
